Nursing Elites

1. The nurse is teaching a client about communicable diseases and explains that a portal of entry is:

• A. a vector.
• B. a source, like contaminated water.
• C. food.
• D. the respiratory system.

Correct answer: D

Rationale: The correct answer is 'the respiratory system.' A portal of entry is the path through which a microorganism enters the body. In the case of communicable diseases, the respiratory system can serve as a portal of entry for pathogens such as viruses or bacteria. Choices A, B, and C are incorrect. A 'vector' is an organism that transmits disease, not the entry point for pathogens. Contaminated water or food can act as sources or reservoirs of disease-causing microorganisms, not portals of entry.

2. The nurse in the emergency room is admitting a client who has sustained a gunshot wound and will require immediate surgery. The client is unconscious and by themselves. Which of the following actions is most appropriate?

• A. Call the charge nurse and request that the facility's legal counsel provide a waiver for informed consent.
• B. Attempt to stabilize the client in the emergency room until they are conscious enough to provide informed consent.
• C. Try to locate the client's family to obtain informed consent before transporting the client to the operating room.
• D. Proceed with transporting the client to the operating room without obtaining informed consent.

Correct answer: D

Rationale: In emergency situations where a client is unconscious and requires immediate surgery to save their life, the priority is to proceed with necessary interventions without delay to ensure the best possible outcome. Obtaining informed consent is essential in healthcare, but in situations where a delay in treatment can be life-threatening, healthcare providers are ethically and legally permitted to proceed with treatment without consent. Attempting to stabilize the client until conscious enough to provide consent or trying to locate family members for consent would cause a dangerous delay in critical care. Therefore, the most appropriate action in this scenario is to transport the unconscious client to the operating room for immediate surgery.

3. A new mother asks the nurse, 'I was told that my infant received my antibodies during pregnancy. Does that mean that my infant is protected against infections?' Which statement should the nurse make in response to the mother?

• A. The immune system of an infant is immature, and the infant is at risk for infection.
• B. The transfer of your antibodies protects your infant until the infant is 12 months old.
• C. Yes, your infant is protected from all infections.
• D. If you breastfeed, your infant is protected from infection.

Correct answer: A

Rationale: The transplacental transfer of maternal antibodies supplements the infant's weak response to infection until approximately 3 to 4 months of age. While the infant starts producing immunoglobulin (Ig) soon after birth, it only reaches about 60% of the adult IgG level, 75% of the adult IgM level, and 20% of the adult IgA level by 1 year of age. Breast milk provides additional IgA protection. Although the immune system matures during infancy, full protection against infections is not achieved until early childhood, putting the infant at risk for infections. Choice B is incorrect because maternal antibody protection typically lasts around 3 to 4 months, not until the infant is 12 months old. Choice C is incorrect as infants are not shielded from all infections due to their immature immune system. Choice D is incorrect because while breastfeeding offers extra protection, it does not guarantee complete immunity against infections.

4. Which situation is an example of the use of evidence-based practice in the delivery of client care?

• A. Encouraging a client who has had a stroke to consume thickened liquids and soft foods
• B. Picking up a dislodged radiation implant with long-handled forceps and placing it in a lead container to minimize radiation exposure
• C. Pouring 1 to 2 mL of sterile solution that will be used for wound cleansing into a plastic-lined waste receptacle before pouring the solution into a sterile basin
• D. Blowing on a fingerstick site to dry it after cleaning the site with an alcohol swab

Correct answer: C

Rationale: Evidence-based practice is an approach that integrates client preferences, clinical expertise, and the best research evidence to deliver quality care. Pouring sterile solution into a plastic-lined waste receptacle before using it for wound cleansing reflects evidence-based practice by preventing the entrance of harmful bacteria into the wound. Option A is incorrect because encouraging a stroke client to consume thickened liquids and soft foods is appropriate, not thin liquids and foods that pose a choking risk. Option B is incorrect as picking up a radiation implant with long-handled forceps to minimize radiation exposure is a safety measure, not evidence-based practice. Option D is incorrect because blowing on a fingerstick site after cleaning can recontaminate the site, which goes against best practices in infection control.

5. Which type of diet should the nurse provide to help a client who has major burns maintain a positive nitrogen balance?

• A. high protein
• B. high carbohydrate
• C. low carbohydrate
• D. low protein

Correct answer: A

Rationale: Clients with major burns are in a hypermetabolic state, leading to increased protein catabolism. Therefore, a high-protein diet is essential to help them maintain a positive nitrogen balance and support wound healing. High carbohydrate diets do not directly contribute to achieving a positive nitrogen balance, making choice B incorrect. Similarly, low carbohydrate diets are not recommended for clients with major burns as carbohydrates provide essential energy needed for healing. Low protein diets are contraindicated for clients with major burns as they require higher protein intake to support tissue repair and prevent further breakdown.
